Oregon Zip List

Oregon Zip list

Standard black text means the post office has been shot and is in the photo album. Red means I have either not driven by or could not find an old PO on a drive-by. Blue means that someone else's photo temporarily occupies the spot. Once the page is entirely black you can consider my job done.

ZIP Codes 97000-97999 are all in Oregon. The numbering scheme is as follows:

970xx: Portland suburbs, (but excluding Portland) and east to Sherman County

971xx: NW Oregon, including north coast

972xx: Portland and adjacent communities in Clackamas and Washington counties

Within each 3-digit designation, numbers are issued in the following manner: The main post office is given the -01 ZIP Code (Salem 97301). Some space may or may not be reserved (-02 to -19, for instance). The rest of the communities in the area are then alphabetized and issued numbers in that order. Generally you will see the A- communities at the top of the list and the Z- communities at the bottom. In some cases, post office names may be out of order. One reason could be that a rural post office is served by another larger one as in the case of the closed out McCoy (97339) having been served by Dallas (97338).

Italicized entries are defunct ZIP Codes that are no longer recognized. Most of these communities' postal services have been absorbed by a neighboring community. Some of these ZIP Codes have been re-issued (such as 97339 from McCoy to Corvallis).

Trivia:

970-, 971-, and 979- do not follow the -01 nomenclature. In these cases Portland is the -01 for 970- and 971- and Boise, Idaho is the -01 for 979-. Portland is also the -01 for Washington's 986-.

ZIP Codes mostly follow county lines. Cases where they do not would include a post office and ZIP Code closing out to the most convenient post office across a county line.
